Summary
City animal services won't release a dog, cat, or ferret for adoption unless it's already sterilized or the new owner signs a sterilization agreement. Owners who sign the agreement must get the animal fixed by an age-based completion date, typically 30 days after adoption, and confirm it in writing to the shelter afterward.
The new owner of an animal adopted from city animal services shall cause that animal to be sterilized by a veterinarian not later than the sterilization completion date specified within the adoption receipt and sterilization agreement executed at the time the animal is adopted. The sterilization completion date shall be:(1)The 30th day after the date of adoption of a dog or cat which the animal control officer estimates to be six or more months old, or the 30th day after a specified date estimated to be the date an adopted dog or cat becomes six months old...or(3)The 30th day after the date of adoption of a potbellied pig which the animal control officer estimates to be three or more months old, or the 30th day after a specified date estimated to be the date an adopted potbellied pig becomes three months old.

Full Breakdown
Section 3-25(b) bars city animal services from releasing a dog, cat, or ferret for adoption unless the animal has already been sterilized, or the new owner signs an adoption receipt and sterilization agreement taking on that responsibility. Section 3-26 sets the deadline: the sterilization completion date is the 30th day after adoption for a dog or cat the animal control officer estimates to be six or more months old, the 30th day after adoption for a ferret estimated at four or more months old, and the 30th day after adoption for a potbellied pig estimated at three or more months old, with the deadline pushed to the next business day if it lands on a weekend or city holiday.
City animal services can grant a one-time 30-day extension, or waive the requirement, if a licensed veterinarian submits a written report stating surgery could jeopardize the animal's life or health; a fresh report is required for each extension request. The rule does not apply to potbellied pigs, wait, it does not apply to what the code calls "pet animals" offered for adoption. Section 3-27 then requires the new owner to deliver a veterinarian-signed letter confirming sterilization to animal services within seven days of the surgery, describing the animal's breed, sex, age, and color and stating the date it was sterilized.
If the animal dies or is lost or stolen before the deadline, Sections 3-28 and 3-29 substitute a signed letter reporting that instead, also due within seven days.
Violations & Fines
Failing or refusing to deliver the required sterilization, death, or lost-and-stolen letter is itself a Chapter 3 violation under Section 3-30. Under Section 3-31, if animal services never receives the confirmation within seven days after the completion date, it may reclaim the animal from the new owner, order its return, or impose any other penalty allowed under the chapter, and the owner gets no refund of adoption fees.
